Is there a way to disable the intro video of Skyrim?

Yes, it is.

Go to your Skyrim folder. Inside this folder there should be a folder called "Data". Inside this folder should be a folder called "Video". Delete the video called: BGS_Logo.bik

It should be the only video inside the folder. I have also tested and verified this works (and doesn't break the game). It just puts you on the start menu where you can load or start a new game.

Possible locations, replace the path where applicable, check the (x86) folder on 64-bit systems.

• %ProgramFiles%\Steam\SteamApps\Common\Skyrim\Data\Video\BGS_Logo.bik

• %ProgramFiles%\The Elder Scrolls V Skyrim\Data\Video\BGS_Logo.bik

• Go to %USERPROFILE%\My Documents\My Games\Skyrim\ or C:\Users\<username>\My Documents\My Games\Skyrim
• Open Skyrim.ini. Navigate to the [General] section.
• Add the following line at the end of the section:
  sIntroSequence=
• Save the file.
